To all top/10m it may concern.'

Be it known that I, CHARLES F. FRAN- cisco, a citizen of the UnitedStates, and a resident of San Diego, in the county of San Diego andState of California, havezinvented certain new and useful Improvementsin Pile Splicing and Driving Devices, of which the following is aspecification:

'Ilhis invention relates to the art of splicing piles where it isdesired to add totheir lengths and for driving piles eitherbelowtor,above the surface of the water or earth, alud it. is more particularlyadapted .for concrete.

piles, and theobjects are, first, to provide'v simple, durable, andeasily installed devices for splicing the ends of two sections ofA apile together, second, to provide` such adevice for facilitating thedriving 'of concrete piles, and third, to provide sucha device fordriving piles where it is desired, to leave the top end below thesurface of the water or the earth.

With these and other'objects in View, as will appear, my inventionconsists of certain novel feature's of construction,combination andarrangement of parts as ivill be hereinafter described in detail and'vparticularly set forth in the appended claims, reference being had tothe accompanying drawings, and to the characters of reference thereon,which form a part of this specification, in which z Figure l is as'ectional view of my device, Fig. 2 is a sectional View thereof throughA-B in Fig/1, and Fig. 3 is an elevational view showing a pile insections, showing my device connecting the ends of two pile sectionstogether, and showing a wooden cushion in connection with' one of themto facilitate the driving of concrete piles.

Similar characters of reference refer to similar parts throughout theseveral views.

My device consists of plastic material 1,.

preferably concrete, shaped as 'shown best in Figs. 1 and 2 and providedwith ahole in` each end, l*1 and lb. It is ellipsoidal shaped exceptthat the ends are iat, and it is provided near its outer surface with awoven wire reinforcement 2, which extends around the same. Inside ofsaid reinforcement surrounding the holes land l", are a plurality ofreinforcingbars 3, shaped as shown best in Figs. 1 and 2. The ends ofthese bars 3 are connected by means of plate 3, which is provided withholes into which said ends are inserted, so that the ends overlap canother therein. In this 4ca se I have shown six of said bars. Thesereinforcing bars are preferably made offtivisted steel, and the innermembers thereof are connected together in their relativ'ge 'positions bymeans of a plurality of connecting bars Al, and their outer members areconnected together by a plurality .of connectingI bars 5. In case it` isdesired to splice two members of a pile, one end of the member-:isplaced .in one of the holes 1a or lbof the device, andl one end .of

as'shown best in Fig, 3, after which thin cement may beflilled in'aroundthe ends of thepme'mbers. In case?` itis desired to use this device fordrivingffpiles, the upper end the other member is placed in the otherhole of the pilel is placed in onelof the'holes la or lb, and intheother hole is placed a short wooden pile 6, as shown in Fig. 3., Thispile 6 acts as a'cushion'betwcen the pile'driver and the concrete pile,Aand it and the device may both be removed .after the pile is driven.vIt will be readily seen that this device is simple of construction,easily installed for use and if composed .of concrete, reinforced asdescribed and shown, it is very strong and substantial. l

Though l have shown and described a particular construction andreinforcement, Il do not wish to be limited to this construction andreinfoncement, but desire to include in my inventipn, the constructionand reinforcemeint substantially as set forth in the appended claims. j

, Having thus described my invention, what I claim as new and desire tolsecure by Letters Patent is 1.-A pile splicing and driving devicecomprising, an ellipsoidal shaped piece made ofgplast-ic material,provided with a hole in eachy end, longitudinally andlaterallyreinforced, all substantially as set forth.

2. A pile splicing and driving device comprising, an ellipsoidal shaped'concrete piece,. provided with a hole in each end, extending nearly tothe center, woven wire reinforcement near the' outer surface of saidplastic fpiece, longitudinal reinforcements between sald holes and saldouter surface and connecting reinforcements, all substantially as setforth.

. 3. In a pile splicing and driving device,

the combination of an ellipsoidal shaped concrete or plastic materialpiece, provided with a iiat surface on .each end and holes therein andlongitudinally and laterally reinforcedl by means of woven wire andtwisted steel bars, and an elastie'pieoe'adapi'iefl to't into one of theholes therein, all Yslilasimitially as set foi-tof f Il, A pile Splicingand driving device, eomjfwieiiig a reinforced ellipsoidal concreto op(lywith fiat ends, and a receso iii each 'end thereof adapted to receivethe nel of a. pile, all substantially as set forth. y
